How A/C Works
This section hopefully answers any questions you may have, such as how the system works, as well as some tips on how to get the best out of your car air conditioning system. If you still have a nagging questions not answered, let us know and we’ll try and help.
Your car air conditioning may not be working due to a number of reasons. Such as it does not have enough refrigerant, it may have leaked out as it does over time. Or, you may have a fault, such as the compressor no longer functions, or the pressure switch is broken, or not enough oil in the compressor which can make it noisy. A whole host of reasons. If it’s not working, then call a car air conditioning specialist such as ourselves to come and look at it, diagnose the problem and then fix it.
Air conditioning lines
The car air conditioning lines condense cold air (works like a radiator), acts as a filter, pump liquid gas through the system, create cold air intake through air vents and transport gas to each system
The aircon compressor is the heart of an air conditioning system. It takes refrigerant as a low pressure gas, pumps it up to a high pressure gas, and circulates it into the discharge hose. Compressors are much like little engines. Most of them have pistons, piston rings, a crank shaft, and bearings, just like a car engine. They need to have oil circulated through them to lubricate all the moving parts. This oil is mixed into and carried with the refrigerant. That is why running an air conditioner without any refrigerant is like running your cars engine without any oil. We have parts to fit all makes and models.
1. What are the benefits of air conditioning?
The origin of the smell is caused by fungus, bacteria and other microbes growing inside the evaporator core. The moisture-laden environment is very conducive to the growth of these organisms. As automakers downsize components to save space and weight, this problem has been increased. Because the automakers made the evaporator smaller, they added more fins and packed them closer together to increase the efficiency of the evaporator. While this has made the evaporator more efficient, it has also made it more prone to trap moisture that contributes to the growth of these organisms.

3. Does A/C use more petrol?
The answer to this is ‘yes’ it does, but not by much. But then think of the alternatives. You could have the windows open but that would increase wind resistance which can add up to 10% to your fuel consumption, especially at speed. And don’t forget the extra noise and pollution through that open window. Also, it’s worth pointing out that you should run your air conditioning at least once a week, especially in winter as the seals can seize up through non-use potentially costing you more in future in new parts and repair!!!
4. Why does my car need an air conditioning recharge?
You’re air conditioning system can lose up to 15% of its coolant every year, so a 3 year old car may have lost almost half its coolant seriously impacting on the performance of the system and damaging the components involved. You should regularly have the air conditioning systems serviced to reduce wear and tear on the components and help avoid potentially big repair bills. We offer recharging and servicing.
5. Why should I get my air conditioning serviced?
As previously mentioned, through non-use seals can seize. Your car manufacturer when they service your car only test to see if the air conditioning works, not that all the components are working properly and in full working condition. Regular air conditioning system servicing ensures the system is full of coolant, that there are now leaks, the pressure is correct and that the hoses, seals and pipes are all in full working order.
6. What’s the best way to run my air conditioning?
Turn the air conditioning on, ensuring that it’s not set to ‘economy’ mode. When you first get into a hot car, open the windows, ensure that the air vents are set to face level and the system is set up to do the same, not pointed at your feet. Remember cold air falls. Turn the temperature to as low as it will go, and the blower as high as possible. Also make sure that the air is on recirculation mode and not taking air from outside. Better to cool already cooled air!! When the temperature is more comfortable, close the windows and increase the temperature to a more suitable level as well as decreasing the blower speed. You should also point the air vents upwards to ensuring the cold air flows down again.
